My present inventionv relates to improvements in hydraulic pumpsy whichVwhile adapted for various uses, areespecially vdek signed for use insupplying motive; power for ,pushing industrial carriers or vehicles,

such as railway cars', through the tunnels lof kilns for ceramic ware.As thus used in the and therefore to secure niaXimum efficiency, theVequipment must be rugged and durable, requiring a minimum amount ofinterrupservice.- v

So far as I am aware, n0 pumps or pushers, are nowv in use that canattain these desired results atan economicalV cost, and Iv havetherefore devised the present pump for ac-V complishing these purposes.

tions and arrangementsV of parts involving `the motive fluidor hydraulicpump of the upright rectilinear type, and its automatic lubrieatingsystem,wher eby vthe parts ofthe ma chine are compactly arranged and`readily accessible for packing,adjustments, repairs,

etc. l Y

In the accompaying drawings, I have illustrated one complete example ofthe physical' embodiment of my invention whereinvthe `parts are combinedand arranged accordingr to the bestmode I havesovfar devised for.

The eccentric shaft extends horioperatedprefer- 'iii zontally above the pump base and as here shown is providedwith three eccentrics 22 for operating a complementary number of pumpunits each including a connecting rod 23, slide head 24 with the wristpin 25. These slide heads :are cylindricalland inthe formof pistons, andthey reciprocate VKin Athe xupright cylindrical cross heads 26 which arecast .integtral with the .casing .or vhousing ll, and 0 these crossheads are provided withsuitab'le linings as 27.

To each slide head 23 a pump plunger 28 is secured with the lowerthreaded reduced end 29 of the plunger screwed 4'into fa comple- 5mentargT socket 30 of the slide head.

Miovethe'top 13 ofthe/casing th-reelh'o'llow 'pump heads-3l are located,each having abottom boss 32 seated i-n an opening V33 and iselcuredas hyLbolts to thetonl 13. The plungers reciprocate in these heads throughpackingjglands '34 and pack-ing nuts 35 4and 'each head has Ia chamber.'36 `communicating port 37 with the valve chamber '.33 -i-n which arelocated inlet ball valves 39 and outlet valves 40coacting withthei-rrespective valve cessiue'l-.v force thesedharges Ioi" motive fluid ltoithe discharge manifold, and -pipe 6 in a substantially continuous anduniform stream to insure a regular Aand uniform pressure of motivefliuid for therpurpose `of propelling for pushing the kiln carsfor'otlher vehicles. The motive fl-uid is continuously xcirculated andis of course replenished from time to time 'as required.

The suction and discharge manifolds cominunicate with all of the vpumpheads fand eX- 'tend -tfransversely fof the heads with 4bosses 45'seated insockets inthe sidesloi the heads and 'attachingbolts 46 areemployed .to lcllamp 'the linanitolds Ito the heads. vrThe verticalchamihers138 fo-fth'e heads Aare lloore'd with fopen 'ends and theseends are closed 'by removable screw ,'pllugs 4^" to lprov-ide Yfacilemeans of Vgaining at) access 1to 1the pump heads whennecessary.

'The operating par-ts of the several pump units are lubricatedautomatically -byan oil 'pump wh-icl-roperaltes synchronously with themechanism. This lubricating l'oil pump is actuated through the use of fa4cam or eccentric groove 4?? inon'e fac'eio'f'tfhe Igear :119,1and 4thisgear las lseen 1in Fig. .6 'revolvesin the sump 48, for oill, formed'inthe bottom zof theengine base.
